Marking Tools
Permanent part marking directly in the CNC cycle — dot peen, scratch and coolant-driven marking tools. Mount in any standard tool holder. No separate marking station, no manual handling required.
Marking Tool Range
Dot Peen Marking
Scratch Marking
SMT20
Scratch Marking Tool
Spring-loaded carbide needle with 6 mm distance compensation. Engraves fine lines directly in the CNC cycle — letters, numbers, logos. Purely mechanical, no air or coolant required.

SMT12
Miniature Marking Tool
Compact version of the SMT20 with 12 mm shank and 3 mm distance compensation. Designed for small CNC machines, Swiss-type lathes and confined tool magazine spaces.

What is CNC Part Marking?
Part marking — engraving serial numbers, date codes, logos or traceability codes — is required in almost every manufacturing process. Traditionally, parts are moved to a separate marking station after machining, adding handling time and risk of mix-ups.
AKS Teknik marking tools mount in the CNC spindle or turret like any standard cutting tool. The marking operation is programmed as part of the CNC cycle — the machine marks the part immediately after machining, with no manual handling and no secondary station.
Which Tool Do I Need?
- Deep permanent marks on hard materials — serial numbers, DataMatrix, dot-matrix characters → PMT20AL
- Fine engraved lines — logos, text, continuous characters → SMT20
- Compact machines or Swiss-type lathes — limited tool magazine space → SMT12
- No compressed air to spindle — but through-spindle coolant available → HMT20
Frequently Asked Questions
-
What is CNC part marking?
CNC part marking is the process of permanently engraving identification marks — serial numbers, date codes, logos or DataMatrix codes — directly on a workpiece during the CNC machining cycle. The marking tool mounts in the spindle or turret like any standard cutting tool, eliminating the need for a separate marking station or manual handling.
-
What is the difference between dot peen and scratch marking?
Dot peen marking (PMT20AL) creates characters from a series of individual dots struck by a pneumatic needle at high frequency. The result is a dot-matrix pattern, ideal for deep permanent marks on hard materials. Scratch marking (SMT20, SMT12) drags a carbide needle continuously across the surface, producing a fine engraved line — like writing with a pen. Scratch marks are shallower and better suited for cosmetic marking or softer materials.
-
Which CNC machines are compatible with AKS Teknik marking tools?
All AKS Teknik marking tools are compatible with any CNC machining centre or lathe that accepts standard tool holders. The pneumatic tools (PMT20AL) require a compressed air supply routed through the spindle or externally. The scratch marking tools (SMT20, SMT12) are purely mechanical — no air or coolant needed. The HMT20 requires through-spindle coolant (TSC) at 15–70 bar.
-
Can marking tools mark hardened steel?
Yes. All AKS Teknik marking tools use a carbide needle (90° tip, 0.3 mm radius) and can mark materials up to 60–62 HRC. This covers hardened steel, case-hardened gears, bearing races and similar components.
